The AGS Laboratories Difference

The 4Cs

AGS Laboratories

Before there was an AGS Laboratories, there were other diamond grading laboratories. However, their focus was on providing a service limited to the jewelry trade. The members of the American Gem Society felt that the industry, as well as the consumer, would benefit from a laboratory held to a stricter standard of diamond grading—with a founding tenet of consumer protection first and foremost.

What that goal in mind, they created AGS Laboratories. Today, AGS Laboratories remains the only nonprofit diamond grading laboratory created with a mission of consumer protection.
